Fatal NI connect error 12203 resulting huge increase in sqlnet.log file

Question

Hi,
I am getting the following error message in SQLNET.LOG file on the client machine. This is my upload program which takes few hours to complete and during the program run, the size of SQLNET.LOG file keeps on increasing and goes to 100's of MB and it contains only this error repeatedly.
But my program gets connected to Database and does the upload. But the size of SQLNET.LOG file grows like anything. Pls let me know what's going wrong.
ERROR in SQLNET.LOG File -
Fatal NI connect error 12203, connecting to:
(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=BEQ)(PROGRAM=oracle80)(ARGV0=oracle80ORCL)(ARGS='(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))')))(CONNECT_DATA=(SID=ORCL)(CID=(PROGRAM=C:\ORAWIN95\BIN\IFRUN60.EXE)(HOST=IT_DBA)(USER=IT))))

Answer 1

Hi,
Actually I thought this error is appearing in only one of the machines, but when I am figuring out, I found the same error in almost all the client machines.
Though the programs are running fine getting the database connectivity, I am not able to find why it is giving error showing connection through BEQ protocol.
Pls someone tell me why this is happening and how I will find out which protocol it is using.
